there's a 3kg mass on a 30 degree frictionless incline. The mass travels(adsbygoogle = window.adsbygoogle || []).push({}); ddistance and hits a spring with k=400N/m. The spring contracts 0.2 m and brings the block to a stop.

I need to find the distance the block traveled.

F=kx

F=400*.2

F=80N

so the block has to hit with 80N.

what formula would I use to get distance? I am confused because if I used any energy formula (which I know I will have to) the question is in Joules instead of Newtons. What should I do?
